The structure of an extracellular, acidic polysaccharide from Rhizobium meliloti IFO 13336 was studied by a method involving successive fragmentation with specific β-D-glycanases of Flavobacterium M64. The polysaccharide is composed of repeating units of the octasaccharide shown. An acidic component was identified as D-riburonic acid.
